RacingDiffs differential bearing set - Differential type 188L - Repair kit for BMW (E87, E90, E60, E70..)

After year 2006, BMW switched from roller bearings to ball bearings inside their differentials. Afterwards, differentials of this kind were called Type L, as for low friction. Ball bearings have lower friction coefficient compared to roller bearings, but they are way less durable, so whining noise is more than often. This kit provides everything you need to fix noisy differential problem.

Type L differentials can be found in the following BMW models:
- 1 series: E81, E82, E87
- 3 series: E90, E91, E92, E93
- 5 series: E60, E61
- 6 series: E63, E64
- X5 series: E70

How to tell if your differential needs bearings replacement?
Characteristic noise from differential/transmission occurs during acceleration and coast (engine breaking). To distinguish differential bearing noise from the wheel bearing noise, steer left-right like you are warming up tires for the race. If the noise changes its intensity then it is a wheel bearing. If intensity of the noise remains the same, that means differential bearings needs to be replaced.

Repair kit includes:
-1x Crush sleeve shim
-1x Small pinion bearing
-1x Large pinion bearing
-1x Input flange oil seal
-2x Output flange oil seal
